DAVENPORT, Iowa, Jan. 22, 2026 /PRNewswire/ -- Winter is here, and Iowa American Water reminds customers to prepare their home plumbing and water meter from the subzero temperatures with simple tips to help avoid costly repairs and unwanted stress from frozen pipes.

"It's important that customers take steps to protect their pipes from freezing as winter approaches and temperatures steadily drop," said Tony Loete, Iowa American Water Vice President of Operations. "Taking time to prepare and regularly checking on your pipes during extremely cold days will help ensure you and your loved ones stay safe and comfortable and avoid unplanned plumbing repairs and property damage."

To prepare now, customers should:

• Know how to shut off your water: Locate your main water shut-off valve. In many homes, it is located near the water meter or close to where the water pipe enters the home. Hang an I.D. tag on the valve so it can be found quickly during an emergency. Download a tag to print here: https://amwater.com/corp/Customers-and-Communities/Wise-Water-Use/cold-weather-protection
• Test your main water shut-off valve: Once located, test the shut-off valve by closing it. Once completely closed, check sinks and other water fixtures to ensure the shut-off valve is working properly.
• Ball valves generally only require a quarter turn to close.
• Gate valves are generally closed by turning the handle clockwise and should turn easily.
• If the valve does not close easily, it may need to be serviced.
• Bonus: While you are there, check your incoming water service line material! Iowa American Water is working with customers to identify their service line material. If they are found to be made of lead or galvanized steel, they will be replaced in the future.

• Eliminate sources of cold air near water lines: Check for pipes in areas that might be prone to freezing, such as crawl spaces, unheated rooms, basements, garages, and exterior walls. Fix drafty windows, insulate walls around pipes and plug drafts around doors.
• Protect your pipes: Where pipes are exposed to cold, wrap them with insulation or heat tape (even fabric or newspaper can help).

When temperatures stay below freezing:

• Give pipes a helping hand: If pipes run through cabinets or vanities, open the doors to let warmer room temperatures flow in.
• Keep water moving through the pipes: Allow a small trickle of water to run. The cost of the extra water is typically lower than the cost of repairing a broken pipe.

If pipes freeze:

• Shut off the water immediately: Do not attempt to thaw pipes without turning off the main water shut-off valve.
• Thaw a frozen pipe by warming the air around it: Use a hair dryer, space heater or hot water. Do not leave space heaters unattended and avoid using kerosene heaters or open flames.
• Once pipes are thawed: Slowly turn the water back on. Check pipes and joints for any cracks or leaks potentially caused by freezing.

When customers are away from home, consider the following:

• Set your thermostat at least 65 degrees to prevent freezing.
• Have a friend, relative or neighbor regularly check the property to help ensure the heat is working and the pipes have not frozen.
• Consider purchasing a freeze alarm. The alarm will call a user-selected phone number if the inside temperature drops below 45 degrees.
